A friend of mine has a 90 Tohatsu on his Hourston, only one I have seen in town that I've noticed. I would say the thing is mid to early 90's in vintage. He's been running that thing pretty much issue free for 10 years or so since he bought it. I do recall it having one issue but minor. Other than that, not a lick of trouble. Based on what I've seen, I would not hesitate to purchase a boat that had one on it.
